Kourtney Kardashian stepped out with model-actor Luka Sabbat, who's nearly two decades her junior, in Los Angeles on Sept. 14 and in Chicago on Sept. 15. According to a People magazine source, the duo are "having fun" and aren't bothered by the difference in their ages. Things are "pretty new," said the insider, adding that the mother of three is "definitely interested" in the "Grown-ish" star but that "it's not like she calls him a boyfriend." Another source, however, said that Kourtney and Luka have been secretly dating for more than a month and that "all of their friends know she's head over heels" for him. Earlier this month, the reality star made headlines when she briefly reunited with ex-boyfriend Younes Bendjima outside a sushi restaurant in Malibu. The meet-up prompted rumors that the male model sold out his former love to the paparazzi "to squeeze out the last drops of his 15 minutes" of fame from their relationship, which Kourtney called fake news.

Are they or aren't they? After several media outlets reported that Drake and Bella Harris — who were first romantically linked in late August — shared a dinner date in Washington, DC, on Sept. 10, the 18-year-old model took to Instagram to insist that she "did not dine in DC recently" because she was "happily working & dining in NYC everyday" during New York Fashion Week.

In other Drake news, Heidi Klum revealed during a Sept. 11 appearance on "The Ellen DeGeneres Show" that the rapper hit her up in February after she picked him over almost every other male star while playing a game of "Would You Rather?" during her previous appearance on the daytime talk show. Unfortunately for the "In My Feelings" chart-topper, the supermodel met current boyfriend Tom Kaulitz in the brief period of time between her appearance on "Ellen" and when Drake texted her after getting her number from a mutual acquaintance.

Four months after Geena Davis' husband of 17 years, Dr. Reza Jarrahy, filed to end their marriage, things took a dramatic turn for the former couple. TMZ reported on Sept. 5 that the actress asked a judge to dismiss her ex's divorce petition on the grounds that, according to her, they were never legally married. The "Thelma & Louise" star claims that when they tied the knot in New York in 2001, they mutually agreed not to file a marriage license — with the understanding that the marriage wouldn't be legally binding under New York law. Therefore, they have no joint property to split and Reza is not eligible for spousal support. The plastic surgeon, meanwhile, is arguing that in spite of evidence to the contrary, he was under the impression that the marriage was valid.
